简介:
曲线滚轮轴承由一根作为滚子组内滚道的螺栓及一个厚壁外圈组成,螺栓轴的台肩及压在螺栓上的端面挡圈组成了外圈沿两个侧面方向的引导面。当曲线滚轮在平滚道或凸轮盘上运动时,由于外圈的弹性变形,滚轮的内应力加大。因此应用于此种工作情况下的额定负荷选择作为曲线滚轮一栏。

公差: 标准轴承外圈的尺寸公差和旋转精度通常情况下为P0级,但不适合外表面为圆弧的,其公差为
mm,螺栓直径公差为h7。
使用及安装:
当安装曲线滚轮时必须注意螺栓与孔的配合,尽可能无间隙,对于配合孔推荐公差带为H7,轴上的配合孔必须有小的倒角以获得最佳的支承面,紧固螺母必须有防松措施。安装时避免锤击螺栓的挡边。螺栓端面上的槽在紧螺母时配用合适的工具来固定滚轮或用来调节偏心套的位置。螺栓滚道上的油孔应尽可能位于非负荷区。
